The security landscape has changed dramatically in the past couple of years. Attacks are getting more sophisticated and AI is now a common tool, used by both defenders and attackers. Cyber security solutions use AI to protect you better, but cyber criminals also use it to find new ways to attack your business.

So, it’s crucial that your cyber security measures are up-to-date with today’s threats.

This guide will show you steps to improve your business’s cyber security in 2024. This is vital for saving money, as the average cost of a cyber attack runs into thousands and half of all UK businesses were attacked last year.

It’s also essential for protecting your sensitive data and intellectual property, and for avoiding disruptions that could affect productivity or halt it entirely. Let’s get started.

Secure Your User Accounts

The first place to start is to look at user accounts and identity. Start with password security. Ensure passwords have at least eight characters, including upper and lower case letters, numbers, and special characters. Password policies can be enforced across your organisation to ensure everyone complies with this.

Next, implement multi-factor authentication (MFA). Passwords alone have weaknesses; MFA adds an extra layer of protection. This could be a one-time code sent to a mobile device or email, or an app like Microsoft or Google Authenticator generating unique codes each time you log in.

Consider passwordless solutions like Windows Hello for Business or FIDO2 keys. These are more secure than using passwords and are quickly becoming the norm.

External Protection

Protect your business from external threats with a modern, industry-grade firewall to guard against attacks like denial of service attacks. Use content filtering solutions to prevent staff from accessing harmful content. At Coretek, we recommend Sophos for this.

Secure Your Devices

Securing company devices is crucial. Things have moved on from having basic antivirus software. These days, it’s important to have a modern endpoint protection solution using EDR and XDR. This might sound technical but it just means using AI and machine learning to detect unusual patterns and protect your business.

Next, ensure devices are fully encrypted; Windows devices come with BitLocker as standard. Keep devices updated with the latest patches. Assign a security policy to every device, whether on-site or remote, using mobile device management (MDM) solutions like Microsoft Intune.

Email Security

Phishing remains the most common form of cyber attack, accounting for 83% of attacks in 2023. Use modern email security solutions that employ AI to detect and block both phishing attempts and spam, keeping you protected and productive.

Make Sure You Have Regular Backups

Have a fallback plan if the worst happens by maintaining regular offsite backups. Traditional data backup remains essential, but also consider options like Microsoft 365 backup. We recommend Barracuda Cloud-to-Cloud Backup for backing up your entire Microsoft 365 suite.


Human error is often the cause of most security breaches. The human is the best firewall after all.

Regular cyber security training for staff is vital but is often one of the first things that businesses overlook. Train staff to spot phishing emails, understand social engineering, and follow best practices for passwords.

You can even use software tools that simulate phishing attempts to test how your staff respond (user awareness training).

Implement a Company Security Policy

Finally, make sure your business follows a clear set of security guidelines that establish a minimum baseline level of security.

At Coretek, we offer audits to assess your current security levels and help you meet required standards for both internal systems and Microsoft 365. If you need assistance or have any questions about any of the advice in this article, contact our team today.

Now it’s Your Turn

By following all of these steps, your business will be better protected and prepared for today’s cyber security threats. Good luck!
